A protective response of the body to infection, irritation or other injury, aimed at destroying or isolating the injuries and characterized by redness, pain, warmth and swelling.
A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.
Localized reaction of the body tissues to invasion by pathogenic microorganisms, or to trauma by wounds, burns or chemicals, which serves to destroy, dilute, or wall off both the injurious agent and the injured tissue. It may be acute or chronic and is characterized by some or all five cardinal signs: redness, swelling, pain, a rise in temperature, and loss of function.
Part of the body’s immune response to heal and repair damaged tissue and defend against foreign invaders, like bacteria and viruses; inflammation can be harmful if it becomes chronic.
Bodily response to an injury, infection, or antigen; prevents the spread of damaging agents, disposes of pathogens and cellular debris, and sets the stage for tissue repair.
Localised protective reaction of tissue to irritation, injury, infection, chemicals, electricity, heat, cold or microorganisms. Characterised by pain, redness, swelling and possible loss of function.
Localised swelling, redness and pain as a result of an infection or injury.
The body’s natural response to trauma, toxins, or infection, in which injured tissues release a variety of substances that increase blood flow to the area. White blood cells arrive to remove dead tissue and other debris. These and other vascular changes produce heat, swelling, and redness; pain or stiffiness often ensue until healing occurs.
Protective tissue response to injury or destruction of body cells characterized by heat, swelling, redness, and usually pain.
A reaction of the body’s tissues to injury or illness, characterized by redness, heat, swelling, and pain. A mechanism of defense and repair.
A reddening of tissues resulting from irritation. Irritation may originate from infection, chemicals, mechanical trauma, or radiation.
The fact of having become sore, red and swollen as a reaction to an infection, an irritation or a blow.
The reaction of tissue to any type of injury.
Response of the tissues of the body to irritation or injury, characterized by pain, swelling, redness, and heat. The severity, specific characteristics, and duration of the inflammation depend on the cause, the particular area of the body affected, and the health of the person.
The protective response of body tissues to irritation or injury.
Tissue reaction to an injury or irritant; symptoms include redness, heat, and pain.
Redness, swelling, heat, and pain in a tissue that conies from the body’s protective response to chemicals, or physical injury, or to infection. When body tissues are damaged, specialized mast cells release chemical substances such as histamine. Histamine increases blood flow to the damaged tissue, which causes redness and heat. It also makes the capillaries leaky, so fluid oozes out of them and into the tissues, causing localized swelling. A person feels pain from the stimulation of nerve endings by the inflammatory chemicals. Inflammation is accompanied by a flood of white blood cells into the affected area, as part of the body’s effort to expel invasive microorganisms and repair damaged tissue. Although inflammation is an essential element in the body’s response to injury and infection, sometimes it brings an unwanted reaction. For example, in allergies, the body mistakenly identifies normal substances as intruders and in an inflammatory response attempts to expel them. This results in uncomfortable symptoms that may include nasal congestion or skin rashes. Treatment is with medications such as antihistamines and corticosteroids.
The immediate defensive reaction of tissue to any injury, which may be caused by infection, chemicals, or physical agents. It involves pain, heat, redness, swelling, and loss of function of the affected part. Blood vessels near the site of injury are dilated, so that blood flow is locally increased. White blood cells enter the tissue and begin to engulf bacteria and other foreign particles. Similar cells from the tissues remove and consume the dead cells, sometimes with the production of pus, and the process of healing commences.
The reaction of the tissues to any injury, which may be the result of trauma, infection or chemicals. Local blood vessels dilate, thus increasing blood flow to the injured site. White blood cells invade the affected tissue, engulfing bacteria or other foreign bodies; related cells consume any dead cells, thus producing pus, after which the site starts to heal. The patient feels pain and the affected tissue becomes hot, red and swollen and may not function properly. If the infection is severe it may persist locally (chronic inflammation) or spread elsewhere in the body (systemic infection).
An immunological defense against injury, infection, or allergy, marked by increases in regional blood flow, immigration of white blood cells, and release of chemical toxins. Inflammation is one mechanism the body uses to protect itself from invasion by foreign organisms and to repair tissue trauma. Its clinical hallmarks are redness, heat, swelling, pain, and loss of function of a body part. Systemically, inflammation may produce fevers, joint and muscle pains, organ dysfunction, and malaise.
The immune system’s reaction to an illness, irritation, or injury that results in heat, pain, redness, and/or swelling.
A reaction to injury or infection that is characterized by pain, redness, and swelling.
A condition in which the body reacts to injury, irritation, or infection; characterized by redness, heat, pain, and swelling.
A characteristic reaction of tissues to injury or disease; it is marked by four signs—swelling, redness, heat and pain.
A tissue’s immunologic response to injury, characterized by mobilization of white blood c ells and antibodies, swelling, and fluid accumulation.
The body’s response to injury; it fights infection and promotes healing.
An immune response of the body to damaged tissue or infection characterized by swelling, pain, heat, and/or redness.
Heat, redness, swelling, and pain caused by trauma, infection, allergic reactions, or other stress or injury to the tissue.
Pain, redness, swelling, and warmth that typically arise in reaction to injury or illness are common manifestations of inflammation.
Inflammation refers to redness, swelling, heat, and pain in a tissue caused by injury or infection. When body tissues suffer damage, mast cells release chemicals like histamine. Histamine promotes increased blood flow to the damaged area and makes blood capillaries more permeable, causing fluid to seep out into the tissues, resulting in localized swelling. The inflammatory chemicals also stimulate nerve endings, leading to pain. Typically, inflammation is accompanied by a local increase in the number of white blood cells, which play a crucial role in destroying invading microorganisms and aiding in the repair of damaged tissues.
Corticosteroid drugs or nonsteroidal anti-inflammatory drugs (NSAIDs) can be used to suppress inflammation.
